Sorry for my poor english。

I have a cluster with 6 nodes，it running OK over six months。
today，I found the icon of node6 is red fork，all vms on nodes is grey with only vmid(without name).
Then I run "pvecm nodes" in console，the result is normal，6 nodes are online.

I have restart pveproxy service on all nodes，How can I do to make the cluster return to normal.
 
Make sure 'pvestatd' is running on all nodes. Also make sure you have correct system time on all nodes. What is the output of

# pvecm status

and 'pvecm status' show the error on all nodes:
